In the framework of the dynamical supersymmetry breaking we construct
the messenger sector as the effective theory of supersymmetry breaking
sector, which is based on the SU(3) x SU(2) model of Affleck, Dine an
d Seiberg. In our model, messenger superfields with the non-renormaliz
able interaction are contained. By minimizing the scalar potential, we
show that the supersymmetry breaking can be communicated to the visib
le sector without breaking QCD color. In this model there appear vario
us scales. Supersymmetry breaking scale turns out to be the intermedia
te scale (similar to 10(10) GeV) between the GUT scale and the soft su
persymmetry breaking scale. (C) 1997 Elsevier Science B.V.
